Day 20: Fuel injector flow testing and cooling system test

Finally gave up on putting everything on hold until the capacitor arrives to test the cooling system. I took it outside and hooked it up to my car battery just to see. One reassuring thing is that the swirl that I designed into the jacket continues on as a vortex in the return line. As seen in the second picture.

I pressure checked the fuel system up to its design 400 psi and ran some water tests through it trying to profile the flow rate of the nozzle. I did two types of flow testing. I collected the water, weighed it and divided it by the time. Another (as seen in the video below) where I put a discrete amount of water into the tank and timed it until it emptied.
